MetalcraftINDUSTRIES LIMITED
Easy to use they fasten directly to their supportswhich eliminates the requirements for cleats.Being symmetrical there is no requirements forbraces or nogs to prevent twisting and allows theprofile to be easily lapped for maximum performance.
MS Tophats are manufactured from high strengthgalvanised steel coil, the Z275 minimum coatingprovides good protection in most exposed internalenvironments. Consideration should be givenwhen used in a lined exterior dwelling. Thermalbreaks are required between the tophat andcladding to avoid thermal bridging. Contact withmaterials not compatible with zinc should beavoided.
HANDLING AND STORAGE
The presence of water between the stacked sections will create premature corrosion, it is recommended the sections are separated anddried if this situation occurs. Cutting if requiredshould be done with hacksaws or snips, use ofabrasive disc blades is not recommended.

ie Bending �b � 0.9
Axial �c � 0.85
The self weight of the purlin is not included in theload tables and should be added along with otherdead loads. All loads are ultimate loads forstrength calculations, and serviceability loads fordeflection calculations, all in accordance withNZS 4203: 1992.
1.2 Vertical loads on purlins
The load span tables show �bwu (ultimateuniformly distributed load in kN/m) for establishingthe purlin strength. Any other loading format mustbe specifically designed. The restraints as set outin 2.0. must apply.
wx (applied uniformly distributed load in kN/m) formaximum inwards and outwards load combina-tions, (derived from NZS 4203) is required in orderto establish the strength requirement for the purlin.
The load span tables also show ws (serviceabilityload in kN/m) for establishing the purlin stiffnessbased on deflection at these loads of L/150. Theapplied serviceability load is required for maximuminwards and outwards load combinations.
1.3 Axial Loads with or without Flexure,Symbols:-
N* � Applied ulitmate axial load
�cNuc � .85Nuc � The member capacity incompression (kN).
wx � Applied uniformly distributed ultimateload (kN/m).

1.4.4 For the fully restrained case to apply the abovecriteria must be met on both faces of the channelor Z section.
For Bending about the minor axis, (y axis) and forbi-axial bending, calculations from first principlesmust be carried out.
1.5 Purlins:-
Axial load and bending. The same applies as forcolumns with combined axial load and bending.
1.6 Braces:-
The standard bracing channel is limited to a purlinspacing of 3000.
2.0 RESTRAINT2.1 General:-
The following restraints are required to achieve thetabulated loads.
2.2 Roof Purlins with uniformly distributedloading:-
One flange of purlin to have roof cladding withnormal screw fixings. Compression flange notrestrained by roof sheeting to be restrained bylateral braces as shown in the tables. For pitchesover 10� the resultant forces in the plane of the roofmust be allowed for.
2.3 Girts with horizontal loading:-
Vertical loads are carried by the bracing system,with a maximum brace spacing of 3000 andsheeting screw fixed to the girts.
2.4 Roof Purlins with combined axial loadand bending:-
Restraint by braces and roof sheeting to oneflange is required. If the roof sheeting fixing meetsthe criteria of 1.4.3 then the value of �cNuc canbe the greater of OFR or that for the value for thebraced purlin. If both flanges are restrained byscrew fixed sheeting then the fully restrainedcase for axial loads applies. Refer 1.4.4.
2.5 Columns Axial Load only:-

2. Uniformly Distributed load on roof purlins
Design Example
Restraints:- Screw fixed roofing provides a fullyrestrained condition for downwards (or inwards) loading.Braces provide lateral restraint for upwards (oroutwards) loading.
Span L = 10m
Purlin spacing = 1.6m
Derived loadings/m on purlins - from known dead load,live load & wind pressure on the roof
Serviceability ws=0.72 ws=0.24
Calculated
Ultimate Load wx=0.89 wx=0.99
Serviceability:- Maximum deflection or = L
150
Try: 250/15 From load span tables
for 10.0m span ws=0.72
Therefore: 250/15 OK
Ultimate Loads:-
Check: 250/15 From load span charts for
10.0m span & 2 braces �bwu� 1.23 � 0.89
10.0m span fully restrained �bwu� 1.63 � 0.99
Therefore: 250/15 with 2 braces is OK
3. Uniformly Distributed load on roof purlins plus axial load
Design Example:- As in 2. but an axial load extendedon the purlin from wind pressure on the end wall of thebuilding
Span L = 10m simply supported
Purlin spacing = 1.6m
Axial load N* = 15kN
Ultimate loads = Wx=0.89 Wx=0.99
Try: 250/18 purlin with 2 braces
the interaction equation is

Cmx wx � 1.0�c Nuc �bwu �nx
Loads:- Outward Inward
N* outwards load = 15 = 0.296�c Nuc (from table) 50.76

Design Considerations
1. All loads on members are uniformly distributed andshown in kilonewtons per metre.
2. All spans for continuous lapped members and doublelapped spans are assumed to be equal.
3. All loadings are Limit State in compliance with NZS4203:1992. The self weight of the purlin is not includedin the load tables.
4. These tables are for use by structural engineers and itis assumed they will derive linear loads inwards andoutwards on the members. The derivation of loads isnot shown in the example calculations.
The tables are based on a total lap length between boltcentres being equal to 10% of the span or 600mmwhichever is the greater. Minimum bolt size M168.8/S. Because the compression flange varies fromtop to bottom it will in nearly all cases not be restrainedby screw fixed sheeting. Therefore the bracedcondition will normally apply for all lapped purlins forboth inwards and outwards loads.
The fully restrained condition only applies where boththe top and bottom flanges are held against lateralmovement by screw fixed sheeting.
The serviceability load (ws) is the uniformly distributedload (kN/m) at which the midspan deflection equals
The standard bracing channel is limited to a purlinspacing of 3000.
Use of tables (UDL = Uniformly distributed load)
5. For the end bays, internal spans and double spans.
Calculate Ultimate UDL Inwards
Calculate Ultimate UDL Outwards
Serviceability wind UDL Inwards
Serviceability wind UDL Outwards
Serviceability DL at deflection limit = L300
6. Calculate the Purlin required.
NOTE: Generally the fully restrained condition does notapply as both flanges are not normally screwfixed to sheeting.
Design ExampleConsider a large supermarket with 10.5m spans over 10bays and purlins at 2.2 centres top flange only fastened tosheeting.

BRACING SYSTEMSMetalcraft has two bracing systems, Camlok™ and Standard. All Purlins and Girts should be braced to maximizethe design limit of the component. It is recommended that at least one row of bracing be used on any span, particularly if temporary loads may be experienced during construction. If the bracing is required to support superimposed dead loads (eg: lighting, sprinklers) specific design will be required.
Camlok™ is a solid bracing system that has no sag rods to place and no bolts or washers to fix. This has proven tosave up to 75% of time in Bracing installation, giving considerable cost advantages.
Metalcraft MSS Purlin and Girt system has been designed for bolting to cleats using the tables provided for hole andcleat dimensions. M12 or M16 Class 4.6 bolts and washers must be used. Design Engineers should give consideration to the bolt diameter, washer size and cleat material and thickness to be used also considering the reaction caused by double or continuous spans and high loads. The bracing systems are formed from galvanisedGrade 250 steel.

The MC Section purlin single span charts can be readilyadapted for floor joist design.
STRENGTH DESIGN
With screwed down sheet flooring the fully restrainedcondition would apply otherwise lateral braces arerequired. The purlin load span charts will apply for the calculated linear loadings on each joist.
Refer Page 3 for Producer Information.
Refer Pages 4 & 5 for Design Considerations
Refer Page 23 for Purlin Bracing Hole Sizesand Purlin Bracing Standard Hole Positions.
DEFLECTION DESIGN
The Ws value in the purlin charts is for a deflection limit ofL/150 for serviceability loads. For floor joists this willrequire modification by the designer to a selected limit usually in the range L to L
250 360
For example if a deflection limit of L/300 is required, thenthe Ws (serviceability linear loading) value in the chart (forL/150 deflection limit) would need to be halved.
CONTINUOUS SPANS
For continuity over two or more spans specific calculationswould be required.

MS Tophats comply with the New Zealand BuildingCode, and are designed to AS/NZS 4600: 1996 Coldformed steel structures.
HANDLING AND STORAGE
Care should be taken to ensure MS Tophats are keptdry during transportation and storage. The presence ofwater between the stacked sections will createpremature corrosion, it is recom-mended the tophatsare separated and dried if this situation occurs. Cuttingif required should be done with hacksaws or snips, useof abrasive disc blades is not recommended.
DISCLAIMER
This publication is intended to provide accurateinformation to the best of our knowledge in regards toMS Tophats Sections. It does not constitute acomplete description of the goods nor an expressstatement about their suitability for any particularpurpose.

MetalcraftINDUSTRIES LIMITED
INTRODUCTION
MS Tophat can be used for roof purlins, wallgirts and floor joists, and are an economicoption for these and other applications includingcarports and fencing. They are an economicalalternative to timber and C section purlins forspans up to 7 meters.
Easy to use they fasten directly to theirsupports which eliminates the requirements forcleats. Being symmetrical there is no require-ments for braces or nogs to prevent twistingand allows the profile to be easily lapped formaximum performance.
MS Tophats are manufactured from highstrength galvanised steel coil, the Z275 mincoating provides good protection in mostexposed internal environments. Considerationshould be given when used in a lined exteriordwelling; thermal breaks are required betweenthe tophat and cladding to avoid thermalbridging. Contact with materials not compatiblewith zinc should be avoided.
